.60 GHz OCS mm-wave generation for ROF system based on saturated parametric amplification effect in HNLF[J].Optoelectronics Letters,2010,6(6):443-445 60 GHz OCS mm-wave generation for ROF system based on saturated parametric amplification effect in HNLF 李温静 Key Laboratory of Information Photonics and Optical Communications,Ministry of Education,Institute of Information Photonics and Optical Communications,Beijing University of Posts and Telecommunications； Abstract:       A novel approach to generate 60 GHz optical carrier suppression (OCS) millimeter-wave (mm-wave) signal based on the saturated optical parametric amplification (OPA) effect in high non-linear fiber (HNLF) is investigated. In the proposed system, the OPA effect occurs when the signal and pump with 30 GHz frequency interval are set into the high non-linear fiber. By controlling the length of HNLF, OPA effect saturates, and the pump power is delivered in a large extent to the signal and idler light, so a 60 GHz OCS mm-wave is generated. The system does not need high-speed external modulator, high-frequency vibration source or narrow-band filter, which greatly reduces the cost and improves the stability of the radio over fiber (ROF) system. Results show that the 10 Gb/s downstream signal can be transmitted with negligible power penalty. Hits: 3953 Download times: 252 View Full Text    Download reader
